HTTP Header Viewer

Enter the host address, such as www.content-networking.com in the text box and press "submit" to retrieve and display the HTTP protocol header for that web object.

Try these examples:

• www.cnn.com — because it is a popular host (with a trivial path),
• www.content-networking.com/images/book.jpg — because it has a nontrivial path,
• us.i1.yimg.com/us.yimg.com/i/yahoo.gif — because it is an old favorite and mentioned on page 54 of the book,
• www.web-caching.com — because they use cache control directives.
